pack v0.11.0

This is a beta release of the Cloud Native Buildpack local CLI. This platform implementation should be relatively stable and reliable, but breaking changes in the underlying specification may be implemented without notice. Note that pack is intended for local image builds, and thus requires a Docker daemon. The lifecycle should be used directly when building on cloud platforms.

Prerequisites

  • The Docker daemon must be installed on your workstation or accessible over the network.

Install

macOS

If you're on macOS, you can use Homebrew:

$ brew install buildpacks/tap/pack

Linux

On Linux you can use the one of the following methods of installation.

Arch Linux
Command
(export GH=buildpacks/pack; export LATEST=$(curl -s https://api.github.com/repos/$GH/releases/latest | grep -o -E "https://.+?-linux.tgz" | head -1); echo "$LATEST"; curl -sSL "$LATEST" | sudo tar -C /usr/local/bin/ --no-same-owner -xzv $(basename $GH))

Others

Otherwise:

  1. Download the .tgz or .zip file for your platform
  2. Extract the pack binary
  3. (Optional) Add the directory containing pack to PATH, or copy pack to a directory like /usr/local/bin

Run

Run the command pack.

You should see the following output

Usage:
  pack [command]

Info

Builders created with this release of the pack CLI continue to contain lifecycle v0.7.5 by default.

Features

  • Performance and security improvements (learn more)
    • Trusted builders (#634, #644)
    • Run analyze, restore, and export via a trusted lifecycle image (#631)
    • Run creator from the lifecycle (#595)
  • Hide stack mixins for inspect-builder behind --verbose option (#630)
  • Add .cnb file support for package-buildpack dependencies (#633)
  • Support .cnb files in create-builder (#611)
  • Overwrite permissions in zip files for FAT formatted entries (#598)
  • Error when --publish and --no-pull are used in an unsupported fashion (#594)
  • Adds experimental flagging (#576)
  • Add Google builder to suggest-builders (#637)
  • Update suggest-builders to use Paketo builders instead of Cloud Foundry builders (#559)
  • Support windows containers for create-builder [experimental] (#571)
  • Support buildpacks from buildpack registry for create-builder and build [experimental] (#540)

Fixes

  • Propagate verbose logging flag to analyze and build phases (#636)
  • build ... --publish now respects default process type (#602)
  • Support substitution for config files such as from envsubst (#592)
  • Remove daemon access from restore phase (#589)
  • create-builder can now handle when both uri and image buildpacks as provided (#625)

Breaking Changes

  • Network mode is now respected for all phases of the lifecycle (#595)
    • This means that publishing (--publish) might be impacted if the network mode does not have access to the registry to which the image is being published to. Previously, analyze and export phases used host network mode when publishing and now use the default (aka bridge) network mode.
    • Related conversations: Slack
    • Solution:
      • Network mode can be configured via the --network flag.
  • Builders with lifecycle versions that don't have a published lifecycle image will error (#644)
    • This would only impacts builders that are not trusted.
    • Solutions:
      • Set builder as trusted via pack trust-builder ... or pass --trust-builder to the build command.
      • Update builder to use the latest versions of supported lifecycle versions.
